During last year’s outbreak of Middle East respiratory syndrome in South Korea, about 20 percent of hospital patients in close contact with a single MERS case, known as Patient 14, contracted the disease, South Korean researchers found after reviewing medical records and security footage.

From May to July 2015, South Korea experienced the biggest outbreak of MERS outside of the Middle...

An experimental vaccine against the MERS virus triggers immune protection, a new study finds. The lethal Middle East respiratory syndrome, caused by a coronavirus that spreads from person to person, can lead to pneumonia.

The vaccine contains DNA much like the virus uses to encode a protein for cell entry. Two of three vaccinated dromedary camels — known carriers of the MERS virus —...

By mining the immune cells of a patient that beat the MERS virus, scientists have identified a protein that could help prevent and treat the deadly disease.

When tested in mice, the protein targeted the virus that causes Middle East respiratory syndrome. The protein could be used to develop vaccines or treatments to protect people from the MERS virus, an international team of researchers...

No obvious changes in the MERS virus account for its rapid spread in South Korea, a report by the World Health Organization says.

Researchers in South Korea analyzed the genetic makeup of the Middle East respiratory syndrome, or MERS, coronavirus from a traveler who was infected on a business trip to the Middle East. The man fell ill after he returned to South Korea and set off an...

South Korea has closed schools and canceled some public events amid concerns that an outbreak of Middle East respiratory syndrome, known as MERS, could become a pandemic. But officials from the World Health Organization say they expect standard infection-control measures to contain the outbreak. So far, the virus has been known to spread between people mostly inside of hospitals and among...

Genetic fragments of MERS, the Middle East respiratory syndrome coronavirus, have been detected in the air of a Saudia Arabian camel barn. The new study, published July 22 in mBio, suggests that more research needs to be done to determine if the virus can be transmitted through the air.

An experimental drug that shuts down construction of virus-making factories could become a new weapon against MERS and similar respiratory diseases. The chemical, called K22, halts growth of a panel of different coronaviruses, including the strains that cause MERS and SARS, researchers report May 29 in PLOS Pathogens.

Two Florida health care workers who reportedly fell ill with flulike symptoms after coming in contact with a patient suffering from MERS have tested negative for the virus, according to health officials.

Officials stressed that there is no significant health threat to the general public and said that the patient with MERS,...

A second health care worker who traveled from Saudi Arabia to the United States has contracted the MERS coronavirus, according to the U.S. Centers for Disease Control and Prevention. Despite the report of the second case, the risk of MERS infection to the general public is extremely low, CDC director Tom Frieden said during a May 12 press conference.
